All it takes Minnesota-based artist Gregory Euclide to create amazing artworks on whiteboards in class is 25 minutes. He decided to start doing these “doodles” as a stress reliever a while back and he has continued to create one picture every day since. Amazingly despite the quality of his work he still erases his artwork every day to make way for new material. He uses sumi ink, brushes, spray bottles, erasers, paper towels and pretty much anything else he can get his hands on around his desk.
